A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Low‐Voltage and High‐k Properties of Bilayer HZO Capacitors at the Morphotropic Phase Boundary for Next‐Generation Memory Applications

Advanced Science, EarlyView.
The HfxZr1‐xO2‐based ferroelectric/antiferroelectric bilayer capacitor exhibits morphotropic‐phase‐boundary behavior with a high dielectric constant (∼52) at 2 V. Phase engineering stabilizes o/t‐phase coexistence and suppresses m‐phase formation, enabling capacitance enhancement and self‐optimization under cycling for scalable low‐voltage, high‐κ ...

Spin Hall Nano‐Antenna

Advanced Science, EarlyView.
ABSTRACT The spin Hall effect is a well‐known phenomenon in spintronics that has found numerous applications in digital electronics (memory and logic), but relatively few in analog electronics. Practically the only analog application in widespread use is the spin Hall nano‐oscillator (SHNO) that delivers a high frequency alternating current or voltage ...
